GEORGE E. GARON, OF MANCHESTER, NEW HAMPSHIRE.

TIRE CONSTRUCTION.

Specification of Letters Patent.

Application led December 16, 1908. Serial No. 467,889.

To all whom it may concern:

Be it known that I, GEORGE E. GABON, citizen of the United States,residing at Manchester, in the county of Hillsboro and State of NewHampshire, have invented new and useful Improvements in TireConstruction, of which the following is a specication.

`My invention relates to spring wheels for automobiles and othervehicles, characterized by tires embodying metallic springs; and itcontemplates the provision of a simple, strong and light tireconstruction, calculated to refficiently cushion the wheel on which itis arranged, and prevent the transmission thereto of-shock and jar.

.Other advantageous features of the invention will be fully understoodfrom the following description and claim when the same are read inconnection with the drawings, accompanying and forming part of thisspecification, in which:

Figure l is a view of a portion of a wheel equipped with the tireconstruction constituting the best practical embodiment of my inventionofwhich I am aware. Fig. 2 is an enlarged transverse-section takenthrough the tire construction`and the adjacent p0rtion of the wheel.Fig. 3 is a detail transverse section illustrative of the arrangement ofone cross-bar and one spring in the inner channel member of theconstruction. Fig. 4

is a side elevation of one of the springs comprised in the construction,removed.

Similar letters of reference designate corresponding parts in all ef theviews of the drawings.

The wheel to which my improvements are applied may be and preferably isof the ordinary well known construction in that it comprises spokesv aand felly b. Mynovel tire construction is arranged and secured on thefelly b, and is made up of a channel member A, of suitable metal, havingcross,

bars B at suitable intervals, a rim C surrounding and separated by anintervening space from the channel member, and metallic springs Dinterposed between and connected with the cross-bars B of the channelmember and the rim() and having for their purpose to prevent thetransmission of shock and jar from therim to the remainder of the wheel.The connection between the channel member A and the felly is preferablyeffected through the medium of `bolts c and nuts d, and the channelmember A is of greater width than the felly in about the proportionillustrated, so as to contribute to the provision of the desirable broadtread on the wheel. As best shown in Figs. 2 and 3, the cross-bars B ofthe channel member are provided with angular end portions e' which arearranged at the inner sides of the outer portions of the side walls ofthe channel member and are fixed in any approved manner thereto.l

The rim` C may be of any construction Patented Oct. 26, 1909.

compatible with the purpose of my invention, though I prefer to have itcomprise. a ianged metallic portion f, and a tire g, smtably secured inor to the metallic portion and' formed of canvas and rubber or of anyother resilient material suitable to the purpose. At its inner side thetire g is recessed, as indicated by it to receive the nuts on the boltsemployed in the connection of the outer ends of the springsto the rim.

Inasmueh as the springs are identical in construction and are connectedin a similar manner with the channel member A,-a detailed description ofthe spring shown in Figs. 2 and 4 will suffice to impart a definiteunderstanding of all of the springs. The said spring, Figs. 2 and 4, isof a slightly Vless width than the channel member A, and

comprises an inner straight portion i arranged at. the outer side of andbolted or otherwise ixedly connected to the outer, side of 'one of thecross-bars B, and a major portion j which is carried in a curved mannerinwardly and about the said cross-bar B* i. e., between the bar B andthe inner transverse Wall of the channel-member A, and is connected atits outer end with the rim C, preferably through the medium of boltsextending through the spring and the metallic portion f of the rim, andhaving nuts disposed in the before mentioned recesses l1, of the tire g.

The several springs D are spaced apart, as shown in Fig. l, and byvirture of the described relative arrangement of the channel member,springs and rim, it will be manifest that the springs will enable therimto pass over stones and rough places in a roadway without thetransmission of shock and jar to the remainder of the wheel; also, thatthe arrangement of a considerabl portion of each spring in the channelmember A Oincreases theresiliency of the spring and lends strengththereto, and at the same time the relative arrangement of parts may bemade within the scope of my?I claimappended.

'nary conditions is retainedin vertical aline* .cause a large proportionof automobile accition, with the result that the rim under ordiment withtheremainder of the wheel and -yet when necessity demands is enabled tomove laterally to a limited extent so as to clear stones and otherobstructions in its path. It will further be observed in this connectionthat the channel member A holds the springs against undue lateralmovement and avoids the imposition of undue strain on the spring whenthe vehicle equipped With the wheel is making a turn.

In addition to the practical advantages hereinbefore ascribed to myimprovements, it will be noted that the tire construction is simple andinexpensive, and therefore obviates the necessity of employing apneumatic or analogous tire, without unduly increasing the cost of thewheel. A

As before stated, the construction herein illustrated and describedconstitutes the best practical embodiment of my invention of which I amcognizant, but it is obvious that in the future practice of theinvention various changes in the form, construction and Moreover it willbe appreciated that my novel tire construction'will avoid accidents, forit will notl puncture, blow-out or get out of order under a vehicletraveling at a high rate of speed as will pneumatic tires which dents;that the construction is calculated to absorb the shocks at lsprocketand transmission gear and prevent stripping of the same; that theconstruction will not require repairing and so will do away with alltire troubles; and that the springs D are formed and arranged to equallyhelp one another in Y outer portions of the side walls of the chailnelmember at intervals andhaving inwardly 4directed portions arrangedagainst and permanently connected to the inner sides of said side Walls,a metallic rim surrounding and separatedby an intervening space from thechannel'member and having outwardly directed side flanges and alsohaving a tire, of resilient material, 4secured between the said sideflanges, and springs, of a less width'than the space between thesidewalls of the channel member and arranged at equal distances fromsaid sidewalls; the said springs being each connected adjacent to one ofits ends to the outer side of one cross bar of the channel member, andeach having a straight portion, extending outwardl beyond the channelmember, and a curve portion extending inwardly through the space betweenthe bar and the inner, transverse wall of the channel member and thenoutwardly beyond the channel member and connected adjacent its'outer endto the inner side of the metallic rim.

In testimony whereof AI have hereunto set my hand in presence of twosubscribing witnesses.

GEORGE E. GARON.
